brianlsu43,The bags for the two units are rated for 30 microns. For a little more than what the Rockler costs, you can get a more powerful motor with much better bags. I know you asked for help with choosing between the two you mentioned, but thought I add this. I have one of the Penn State's dust collectors , the DC1B-XL. The 1 HP motor is sufficient when connected to one machine, I haven’t tried it with two machines. The collector has casters on them and I move the unit when connecting to a different unit. For me, that’s not a problem but that’s based on each individual’s needs. What I liked about it is that the bags are rated for 1 micron filtering capability. Cutting MDF can make very fine dust. however, my unit is much bigger in size than the ones you are looking at, so if space is a constrain, then that’s another requirement.
